About Brewongle's Climate Risk Profile

Brewongle, NSW, is a suburb that faces increasing climate-related challenges. The primary risks are associated with flooding and bushfires, both of which are projected to worsen under climate change scenarios.

Flooding is a significant concern due to increased rainfall intensity. The suburb may experience more frequent and severe flood events, impacting homes, infrastructure, and transportation. Residents should be aware of flood risks and take necessary precautions.

Bushfire risk is also high, given the proximity to bushland. Hotter, drier conditions and stronger winds can create ideal conditions for bushfires. Property owners should maintain their properties and have bushfire survival plans in place.

Heatwaves are expected to become more frequent and intense, posing health risks to vulnerable populations. It is important to stay informed about heatwave warnings and take steps to stay cool during extreme heat events.

While Brewongle is not directly exposed to coastal risks, the broader impacts of climate change, such as disruptions to supply chains and increased insurance costs, can still affect the suburb.
